I have a pair of Duo 2300c's with a single docking station. The Duos came with a minimal 7.5.2 installed, which is not new enough to put an AppleShare client on, so I upgraded one of them to MacOS 9.1. That's when things got interesting... Because I don't have the rectangular SCSI cable that would fit on the back, I popped the cover of the docking unit and ran a 50 pin SCSI cable from the internal SCSI port to a CD-ROM that's in an old UMAX c500. (All I needed was the CD-ROM and the power supply.) This worked great under 7.5.2, but now that I've bumped up to 9.1, no CD I put in the drive comes up on the desktop. Has anyone seen this before??
